Safety

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the GT-R. But it costs extra on the 911.

Both the GT-R and the 911 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.

Warranty

Nissan’s powertrain warranty covers the GT-R 1 year and 10,000 miles longer than Porsche covers the 911. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the 911 ends after only 4 years or 50,000 miles.

There are almost 6 times as many Nissan dealers as there are Porsche dealers, which makes it much easier should you ever need service under the GT-R’s warranty.

Reliability

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Nissan vehicles are better in initial quality than Porsche vehicles. J.D. Power ranks Nissan 7th in initial quality, above the industry average. With 10 more problems per 100 vehicles, Porsche is ranked 15th, below the industry average.

Fuel Economy and Range

The GT-R has 2.6 gallons more fuel capacity than the 911 RWD’s standard fuel tank (19.5 vs. 16.9 gallons), for longer range between fill-ups.

Transmission

The Nissan GT-R comes standard with an automatic transmission, for driver comfort, especially in the city. Automatic costs extra on the 911.

To facilitate fast shifting and allow the driver to focus on the road, the GT-R has a standard up-shift light to indicate when to shift, based on a value pre-entered by the driver. The 911 doesn’t offer an up-shift light.

Brakes and Stopping

For better stopping power the GT-R’s brake rotors are larger than those on the 911:

Tires and Wheels

For better traction, the GT-R has larger front tires than the 911 (255/40R20 vs. 235/40R19).

For better ride, handling and brake cooling the GT-R has standard 20-inch wheels. Smaller 19-inch wheels are standard on the 911.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the GT-R can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The 911 doesn’t offer run-flat tires.

Suspension and Handling

For a smoother ride and more stable handling, the GT-R’s wheelbase is 12.9 inches longer than on the 911 (109.4 inches vs. 96.5 inches).

For better handling and stability, the average track (width between the wheels) on the GT-R is 1.7 inches wider in the front and 1.8 inches wider in the rear than the average track on the 911.

The GT-R’s front to rear weight distribution is more even (54.7% to 45.3%) than the 911’s (40.1% to 59.9%). This gives the GT-R more stable handling and braking.

The GT-R NISMO executes Motor Trend’s “Figure Eight” maneuver quicker than the 911 Coupe (22.9 seconds @ .92 average G’s vs. 23.5 seconds @ .86 average G’s).

Chassis

To almost totally eliminate engine vibration in the passenger area, the GT-R has a liquid-filled front engine mount. The liquid helps further dampen engine harshness. The 911 uses conventional solid rubber engine mounts.

The design of the Nissan GT-R amounts to more than styling. The GT-R has an aerodynamic coefficient of drag of .26 Cd. That is lower than the 911 (.29 to .32). A more efficient exterior helps the GT-R go faster and keeps the interior quieter. It also helps the GT-R get better fuel mileage.

The GT-R uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The 911 doesn’t offer active noise cancellation.

Passenger Space

Because it has more passenger and cargo room, the EPA rates the GT-R a Subcompact car, while the 911 Coupe is rated a Minicompact.

The GT-R has 9 cubic feet more passenger volume than the 911 Coupe (79 vs. 70).

The GT-R has .1 inches more front headroom, 3.5 inches more front shoulder room, 2.5 inches more rear headroom, 1.4 inches more rear legroom and 1.7 inches more rear shoulder room than the 911 Coupe.

Cargo Capacity

The GT-R has a much larger trunk than the 911 Coupe with its rear seat up (8.8 vs. 5.1 cubic feet).

With its coupe body style, valet key and remote trunk release lockout, the GT-R offers cargo security. The 911’s non-lockable folding seat and non-lockable remote release defeat cargo security.

Ergonomics

The GT-R’s standard power windows have a locking feature to keep children from operating them. Porsche does not offer a locking feature on the 911’s standard power windows.

The Intelligent Key standard on the GT-R allows you to unlock the driver’s door, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Porsche 911’s available Porsche Entry and Drive doesn’t unlock the trunk.

For greater rear passenger comfort, the GT-R has standard rear heat vents to keep rear occupants more comfortable. The 911 doesn’t offer rear vents.
